[Office Partner Information Center] In the process of "serving" inkjet printers for a long time, it is almost inevitable that various strange phenomena will occur. In order to ensure that inkjet printers can work efficiently, many people have frequent occurrences. The inkjet printing failure and the troubleshooting process are summarized, so that once the same fault occurs in the future, it can be prepared and quickly eliminated in a targeted manner.
Fault 1. Recently, the inkjet printer in the office office has to perform automatic cleaning operation almost every day. Is this phenomenon normal? 
Under normal circumstances, inkjet printers generally do not automatically clean the nozzles frequently. If we are unfortunate enough to encounter this phenomenon, most of the inkjet printer's control circuit has failed. The operation of the automatic cleaning nozzle is performed according to the program setting of the inkjet printer and the actual use. If the cleaning nozzle operation frequently occurs or the cleaning operation is continuously performed, it is very likely that the program of the inkjet printer controlling the nozzle is disordered. Phenomenon, at this time we must promptly send to a professional repair station to repair. Considering that inkjet printers are relatively sophisticated mechatronic devices, inkjet printer motherboard control chips can accurately perform paper feeding operations, paper feeding operations, paper ejection operations, and print head movement operations with the cooperation of various precision mechanical components. The target material content is printed on the corresponding printing paper accurately. The problem that the printing nozzles encountered frequently need to be cleaned is not necessarily the problem of the printing nozzle itself, but also the ink supply system, the ink discharging system or even the printing control circuit related to printing may be defective. These factors may cause printing. The nozzle has frequent cleaning operations.
Fault 2: After the inkjet printer adopts the continuous ink supply mode, the print nozzle is damaged, and the inkjet printer nozzles of different models and types are used for replacement. Can this replacement be used?
As we all know, the nozzle is one of the most precise and important components in inkjet printer equipment. In addition to the very strict process flow and production environment required in the manufacturing process, it also covers storage, transportation, installation and replacement. There are strict requirements in the link. Any irregular or inappropriate operation may cause serious damage to the quality of the print head or even be directly discarded. Although in many printer models, the same series of branded inkjet printers may encounter the common use of the printheads, but the general need for us to replace the installation by manual methods, and this operation often requires high precision. Therefore, we must not use Other types of inkjet printheads to replace them to avoid damaging the output nozzles of inkjet printers, thus causing unnecessary economic losses.
Fault 3: When using an inkjet printer to print out black and white documents, we often find that the printed pages contain colored horizontal lines, and the horizontal lines are irregularly arranged.
When we encounter output color irregularities, ink leakage, plugging, etc., or when using an inkjet printer to print black and white documents with colored horizontal lines, we can probably determine that the above phenomenon is caused by damage to the inkjet print head. In general, there are many causes of damage to the inkjet printhead, but in general it can be divided into hard faults and soft faults. From the above description of the fault, we believe that the inkjet printhead should be physically damaged, so we must promptly send the inkjet printer to the designated repair point to replace the printhead. If the print cartridge is integrated with the printhead, we should not hesitate to replace the entire print cartridge.
Fault 4: An inkjet printer can print a single sheet of paper, but when it prints out more than 2 pieces of content, it will automatically stop printing. At the same time, the power of the inkjet printer will be flashing continuously, when the print user disconnects the print. When the power is turned back on, the print head emits a weird sound, and although the ink jet printer can be normally reset, the above problems occur repeatedly.
In the event of any of the above-mentioned malfunctions, most of the foreign objects accidentally enter the inkjet printer or some of the mechanical parts of the printer have worn out, which causes the printed word car to not run smoothly, and may even cause the printed word car to be stuck. dead. Therefore, in order to extend the service life of the mechanical parts of the printer as much as possible, we recommend that you use paper of a slightly better quality when printing materials, and always close the top cover of the inkjet printer when using and placing the inkjet printer. To avoid the effects of paper dust, air dust, etc. on the mechanical parts of the printer. If some of the printed parts are worn out and the print car is not working properly, we should take the inkjet printer to the designated service station for repair.
Fault 5: When the inkjet printer starts the self-test, the belt and the motor of the printed word car make a strange sound. And this happens every time the printer starts up, but the inkjet printer is normal during the process of printing the material. Is this normal?
In fact, this is a phenomenon that is not normal. Although the inkjet printer may make a sound during operation, there should be no abnormal noise between the belt of the printed carriage and the motor. Once you accidentally encounter the above phenomenon, we should first check carefully if any foreign matter has accidentally entered the inside of the inkjet printer. If foreign matter accidentally enters, it will cause the load of the inkjet printer's word car and related parts such as the motor to increase or scrape the car belt. At this time, we may carefully take out the built-in installation manual of the printer and carefully remove it. foreign matter. If you find that the foreign matter in the inkjet printer has entered a deep position or is stuck, we must ask a professional maintenance person to repair it. Need to remind friends that the reason why this type of printing failure occurs in inkjet printers, it is probably because we use a continuous quality ink supply system and compatible ink cartridges, which is easy to cause ink leakage accidents, and leaked out The printing ink will increase the running resistance of the inkjet printer mechanical parts, and the additional piping of the inkjet printer using the continuous ink supply system will impose an additional burden on the printing carriage and the printing motor.
Fault 6. The inkjet printer has discontinuous color bars appearing during the printing process. When I hit the test page, I found that there was a problem with the distribution of the blue and light blue patches, the position was incorrect, and the problematic holes were still uncertain.
There are two possibilities for this kind of failure. First, there is a problem with the ink cartridge, or the ink is insufficient, or it is not a genuine ink cartridge. Secondly, it may be that the printer is used for a long time, and the components such as the pump and the pump accessory are worn out, resulting in insufficient sealing. The first way to solve the problem is to check if the ink cartridge is installed in the correct position. The user can install the ink cartridges in accordance with the User Manual and the order in which the printer body is labeled. When the nozzle detection sample is broken, you can perform 1 to 2 cleaning operations (the cleaning operation will consume a certain amount of ink, so we recommend not performing the cleaning operation more than 3 times. In addition, to improve the cleaning efficiency, you can also try each The printer is allowed to stand for a period of time between cleaning operations). If the cleaning operation is invalid, it can only be sent to the repair center for repair.
Fault 7. When the inkjet printer is loading the print driver online, the computer system prompts us to find that the inkjet printer device cannot be found. When checking the printer power supply and wiring, we find that they are all normal, and the author has also replaced the new print data. The line, the printer driver used is also downloaded from the official website. When I tried to skip the printer check operation and load the print driver, the inkjet printer could not print properly and prompted an unknown error.
In the case of the above inkjet printer failure, we may wish to carefully check the printer driver and enter its property setting interface to see if the print port settings are consistent with the actual print port. In general, the computer's default printer port must be carefully reviewed and must be changed as soon as the port mismatch is found. Moreover, inkjet printers may have program conflicts during the installation process. For example, when the HP brand's spray is installed on the same computer as the Epson brand, it is prone to incompatibility. We may try to connect the faulty printer directly to other computers to determine if the current fault is caused by the printer hardware or software.
Fault 8. Sometimes we will find that the inkjet printer does not emit ink during the working process, and when cleaning the printhead, the ink lamp and the paper feed lamp in the control panel will be in a long light state, and other signal lights are in the Not lit. When the paper feed and ink lamps in the control panel were pressed by hand, they did not respond.
Unfortunately, when this kind of malfunction occurs, it is very likely that there is a problem in the circuit part of the ink jet printer head, or the head cable is accidentally disconnected, so that the print head electrical signal cannot be normally transmitted. Generally speaking, this kind of printing failure is relatively complicated. It is often impossible to solve the problem through ordinary inspection, so we need to send it to the professional repair center in time to solve it.
